Application May 27, 1933, Serial No. 673,203

Renewed November 16, 1934 16 Claims. (01. 191-1) The present invention relates to a novel device for use in association with a typewriter, which device not only automatically feeds or delivers sheets of paper or the like to the platen roll of said typewriter and places them one after the other in proper writing position thereon and automatically ejects or discharges said sheets from. said platen roll and stores themin their order of succession, thusrelieving the typist of all labor in such positioning, removal and storing of sheets,

lever or the like to start the device operating, but also automatically projects on a visible-screen a record copy of the matter which the operator is to type on the sheets. My invention is particularly useful in the addressing of letters and en-' velopes in large quantities and combines typewriter, automatic sheet feed and discharge and picture projecting apparatus into a unitary structure capable of several uses all of which will become apparent hereinafter.

except to the extent of a throw or touch of a Advertising agencies and business offices often have on file a considerable number of card records of the names and addresses and other data relat-,

ing to the individuals or concerns to whom circular letters, advertising literature or the like are. to be mailed periodically. These cards take up considerable labor being often required to rearrange them in their proper sequence. V I In accordance with my invention I substitute, in lieu/of theaforesaid cards, records of reduced size and of a light-transmitting character, which may conveniently be eontiguously formed along a continuous strip or band of sheet'ma terial. I prefer'to utilize a photographic film,

' such as is used in motionpictur'e apparatus or picture projecting apparatus, which film hasiapplied on its dividing squares, as by photography, the imformative data desired of the various addressees. Qbviously, any other matter, to

which future reference may be desired, may likewise be recorded on said band or film. In connection with the latter, I employ a projecting apparatus which enlarges the minute records and permits them to be successively projected on a visible screen, the enlargement being such that the projected -matter may be readily read ofl. the

screen with the eye positioned at an appreciable distance therefrom.

In the typing of addresses or similar matter in quantity, as in mail advertising, it has generally been the practice of typing'them from the afore- 5 said card records used as a copy. Obviously this has necessitated an expenditure of considerable time and labor, not only in the carrying of the cards from one place to another, often in their more or less heavy trays or containers, but in 10 the repeated manipulating or turning over of successive cards to permit each record. in turn to be read and copied. Furthen'it is quite possible that some of the cards escape notice by being skipped by the typist in her work of successively l5 turning the cards over, so that the advertising matter is not sent to the overlooked parties.

In accordance with a further feature of the invention, the projecting apparatus is utilized in combination with a typewriter so that the typist 20 may observe the projected records from his or her position before said typewriter and utilize said projected records as a guide or copy in his or her work of typing addresses or other matter on letters, envelopes or like sheets, and I provide 25 means whereby said apparatus may be actuated to project a different record for each sheet addressed or t upon. I

Thus, my invention does away with all inconveniences and diiliculties e'ncounteredin connec- 30 .tion with the use of cards, as a system of recording addresses or the like or as a system of copying or typewriting the matter therefrom. I may utilize the smallest size standard film as now employed in motion picture projection. Such a 35 film is about% inch wide'and a foot length contains 8000 squares or' picture areas. On each a of said areas at least five names and addresses may be photographed. It is thus possible to provide a total of at least 40,000 records in a 100 40 foot length of such film, and the latter may be coiled on the usual reel to a roll diameter not exceeding 5 inches. Besides thisvast saving in omce space, my band of records makes loss of some of them impossible and at alltimes pre- 45 serves their proper sequence or order of listing. The projected records are read oil the screen without effort or fatigue to theeye, the additional labor involved in the copying of recorded matter from successive cards being entirely elimi- 9 nated, and there is no chance of a record being .skipped or not coming to the typists attention ingthe usual way as a machine separate from the remaining apparatus; means permitting the record projecting apparatus to be operated by said control, without the automatic feeding and.

discharging apparatus; means permitting the automatic sheet feeding and discharging apparatus to be operated by said control, without the" record projecting apparatus; means for displacing the band of records in either direction; means, independent of said control, for displacing the band of records to quickly bring intoview on the screen any particular record or group or records. I

Since each oi! the dividing squares or picture portions of my continuous band or film oi records may contain a plurality of addresses or records. the invention further comprehends the provision --of means whereby the band is advanced in the projecting apparatus the distance of a picture area only after the right number of letters or sheets have been addressed or typed upon in the typewriter, and I also provide automatic shutter means permitting only a single address or record to be projected at a time on the screen. Since any number or records may be contained within a picture area, I further provide means for regulating the number of times the control must be actuated to cause a displacement of the band of records, so as to have the number of successive records projected correspond to the number of sheets addressed or typed upon. The same controlserves to actuate the shutter means, whereby no error is possible in the sequence of records projected on the screen. For those picture areas each containing a single record, the shutter is rendered inoperative and may be displaced out of cooperative relation with the screen.

These and still further features and objects of the invention will become apparent in the following description of the embodiment of the invention shown in the drawings in which Fig. 1 is a profile view of the complete apparatus, some ot the parts being omitted and others shown in section for purpose of clarity; Fig. 2 is a profile view ofa portion of the apparatus, particularly illustrating the shape of one of the side frame r plates and the belt drive connections to. the conveyor rollers; Fig. 3 is a front view of the apparatus, some of the parts being omitted for purpose of clarity; Fig. 4 is anenlarged plan view, partly in section, of vthe typewriter platen roll 4, and parts associated therewith; Fig. 5 is a crosssectional view of parts, taken on the plane indicated by the arrows 5 -5 in Fig. 4; Fig. 6 is a detail view taken on the plane indicated by the arrows 6 --6 in Fig. 5, particularly illustrating the construction of the cooperating cams shown positioned on a fixed base or desk top 2 to n the plane indicated by the arrows NI -NI in Fig. 4, particularly illustrating parts immediately in the rear of the platen roll and movable therewith; Fig. 10A is a. detail view taken on the plane indicated by the arrows IOA -IUA in Fig. 12, particularly illustrating one of the rear fingers movable with the platen roll; Fig. 11 is a detail view taken on the. plane indicated by the, arrows ll --l I in Fig. 4, particularly illustrating the cooperating cam-grooved wheel and roller-carrying slotted lever, which serve to actuate the suction sheet feedingdevices; Fig. 12 is a view taken on the plane indicated by the arrows I2 -l2 in Fig. 10, particularly illustrating the rear roller and fingers movable with the platen roll; Fig. 13 is an-enlarged profile cross-sectional view of the upper front portion of the projector, particularly illustrating shutter mechanism parts; Fig. 14 is-a rear view taken on the plane indicated by the arrows NI -44 in Fig. 13, particularly illustrating other parts of the shutter mechanism; Fig. 15 is a detail view taken on the plane indicated by the arrows I5 i5 in Fig. 1, particularly illustrating rocking parts for actuating the shutter mechanism; Fig. 16 is an enlarged view of a portion of the apparatus, taken on the plane indicated by the arrows l6 |6 in Fig; 1; Fig. 17 is an enlarged profile view of the film reeling mechanism and other parts associated therewith; Fig. 18 is a plan view of parts, taken on the plane indicated by the arrows Iil l8 in Fig. 17; Fig. 19 is a cross-sectional detail 'view taken on the plane indicated by the arrows I9 l9. in Fig. 1'7, particularly illustrating one of the reels and supporting mechanism therefor; Fig. 20 is a cross-sectional view of details, taken on the plane indicated by the arrows Z|l 2ll in Fig; 17; Fig. 21 is a detail view of the film actuating mechanism clutch control, taken on the plane indicated by the arrows 2l 2I X in Fig.

Referring to Figs. 1, 2 and 3, a typewriter l is.

permit manipulation'of its keyboard and is preferably fixedly secured in this position to said base 2. This typewriter, in so far as its manual opera-- tlon is concerned, is of standard construction, no detailed description or its usual parts being required, but, to adapt it to have sheets automatically fed to its platen roll 4 and positioned thereon, its usual'sheet supporting or guiding plate 5 is formed with a longitudinal slot 6', as best illustrated in Figs. wand 12, and carries at its rear further parts for movement therewith. These additional parts and the particular purpose of the slot 6' will be described hereinafter. or course, the plate 5, as in the usual construction, is in fixed relation with the typewriter carriage and therefore moves laterally in either direction with the platen roll 4.

overhanging the typewriter i are a sheet feeding conveyer 6 and a sheet discharging conveyer 1, each comprising spaced guide plates suitably supported by side plates 8 and 8a fixedly extending Irom the base 2, one or the plates, 0a, being shaped as shown in Fig. 2 to allow proper lateral movement, in either direction, of the typewriter carriage and a sheet therein. As shown by an i inspection of Fig. 3, these conveyors are disposed at one side to cooperate with the typewriter carriage when the latter is in its extreme left position, determined by one of the usual adjustable stops (not shown). The lower portion of the feed conveyer 6 slopes to'the same extent as the typewriter guide plate 5, and, for said position of the typewriter carriage, the lower edge or discharge end of said conveyer 6 is slightly spaced from the-upper edge. of said plate 5 and the latter is in direct alinement with the lower guide plate of said conveyer 6 so as to form a virtual continuation thereof. The discharge conveyer I is positioned above the feedconveyer, a laterally extending hinge 9 being provided to permit its lower portion 1a to be swung from its position shown in Fig. 1 to its position shown in Fig. 2, so as not to hinder the operators movements -when it is desired to remove sheets from the typewriter by hand or both insert and remove sheets into and from the typewriter by hand.

The pivotal portion Ia'may be detachably held in its upper position by any suitable means.

" When in its lower position, the lower edge or intake end of the conveyer I is so positioned relatively to the typewriter that the sheets, as they are ejected, 'when typed upon, by successive rotations or line-spacing actuations of the platen roll 4, or, when the carriage is in its extreme left position, by automatic rotation of the platen roll 4 as will be hereinafter described, enter said con- ;,veyer 1 between its guide plates.

Blank sheets III, or the sheets to be addressed in the typewriter, are fed into the conveyer 6 from avertically movable container or magazine I I, which is provided with an open side contiguous to the intake end of said conveyer 6. The typewritten sheets are discharged from the conveyer 1 into another vertically movable container or magazine l2, which is provided with an'bpen side contiguous to the discharge endof said conveyer i and which stacks the sheets it receives. As will be hereinafter more clearly understood, the apparatus operates to remove the sheets from the magazine H, only one at a time and only one during each operation of the apparatus (for conveyance to and proper positioning on the v platen roll 4), and to advance or store the'sheets into the magazine l2, only one at a time and only one during eachoperation of the' apparatus (after its ejection and conveyance from the posed sheetof the stack in the. magazine I I be maintained at the proper level relatively to the intake end of the conveyer 6, the sheet supply magazine II is displaced upwardly a given d-istance, whenever the stack l0 has been depleted to an extent making this operation necessary. Simultaneously therewith, the sheet storage magazine I2 is displaced downwardly the same distance. The mechanism causing these simultaneous displacements of the two magazines will be described hereinafter. Each of the magazines is equipped with the usual adjustable means (not shown) for properly positioning and stacking th sheets in accordancewith their size.

Each of the conveyors 6 and I also comprises a plurality of belt-driven rollers l4 and a corresponding number .of spring-pressed idlers l5 cooperating therewith. All of these rollers are rotatably mounted on the frame or side plates-6 platen roll .4) Thus, in order that the upper ex veyer acting in turn to engage opposite surfaces 5 of a guided sheet to advance or convey it'in the proper direction, as determined by their rotation.

These rollers are of such length and the cooperating pairs of each conveyer are disposed at such intervals that sheets of varying size may 10 be properly conveyed in the manner described. Thus, the sheet-supply stack I0 may vary in regard to the size of the sheets it contains, a pair of section sheet feeding devices I 6 (only one being shown), to be hereinafter more particularly-del5. scribed, acting to transfer said sheets from the magazine ll seriatim to the first cooperating roller pair I! of the conveyer 6 at its intake end, being thereafter discharged by the last cooperatin'g roller pair I 9 into the lower sloping por- 2 tion of said conveyer 6, through which they travel for-the present), as it travels between the guide 30 plates of said conveyer 1 (by automatic. rotation of the platen roll 4, as will be understood), may be gripped by said pair 20 to be discharged by the last cooperating roller pair 2| of said conveyer 1 into the storage magazine 12 The power for actuating the apparatus is furnished by a motor 22 suitably secured to the base 2. As shown in Fig. 16, the motor shaft drives a pair of cooperating bevel gears 24 and 25, one of these, 25, being secured to the lower efid of a 40 vertical shaft 26 extending through the base 2. Said-shaft 26 is rotatably mounted at itslower end in a bearing 21 forming part of asupport 29 fixed to the base 2 and above the base 2 in a bearing 30 secured to the side plate 8. Said shaft 45 26'is prevented from moving axially and may be mechanically connected at its upper end by a clutching device 34 to a bevel gear 35 rotatably mounted in a horizontal frame piece 35 secured at its ends to the side plates 8 and 8a. A shaft 31 is rotatably mounted in a bearing 39 fixed to the plate 36 and in the side frame plate 811 and I carries at its inner end a bevel gear 40 meshing v with the aforesaid gear 35. At its outer end said shaft 31 carries a double pulley 4|. 55 Referring to Fig. 2 said pulley 4| cooperates with a belt 42 which drives a double pulley 4:

- fixed to the shaft of the roller I4 pr the coopis ro'tatably mounted in the side plates 8 and la. 65

The roller ll 'of the cooperating pair i8 is also provided with a double pulley 41, which is rotatedby the aforesaid double pulley 4| through the intermediary of a full-twist, or cross-belt 49.

producing a reverse motion of the driven roller. 70

The roller [4 of the other cooperating pair" is.

driven by another belt 50 cooperating with said pulley 41. With the motor 22 running and the shaft 26 andgear 35 connected by the. clutching device 34, the various'rollers of the two conveyers 8 and 1 are thus caused to rotate continu ously.

The clutching device 34 comprises a toothed tubular element I fixed to the gear 35 and a coin said gear 35 and element 5|, which are rotatable as a unit. A spring 54 disposed between the element 52 and a fixed collar 55, holds the toothed elements 5| and 52 in mesh. A bell-crank control 58 is pivotally carried by a bracket fixed to the frame piece 38 and has a pin which rides in a circular groove 58 on the slidable element 52 and a detent 59 to cooperate with an opening 88 in the frame piece 38. Said control, when operated to cause the detentto drop into the opening, disengages the clutch elements 5| and 52 against the spring 54. This clutching device 34 permits stopping the rotation of the conveyor rollers,

I when it is desired to insert and remove sheets on and from the platen roll 4 by hand. Its control 56 may be manipulated through an opening 8| in the side frame plate 8. A worm 82 is fixed to the actuating shaft 28:

and, as shown in Fig. 4, meshes with a wormwheel 84, which therefore rotates continuously. Referring to Fig. 7, said wheel 84 is"loosely engaged by a shaft 88 so as to be rotatable thereon.

Said shaft. 88 is rotatably mounted in the side frame plate 8 and in a bearing 85 secured to the frame piece 38, a fixed collar 89 preventing outward movement thereof. The wheel 84.is provided with ahollow toothed hub or clutching member 1|, within which a collar 88, fixed to the shaft 88, is disposed. The collar 88 and the 14 inwardly and holding the latter locked to the clutching member 1| These members 1| and 14,

however, are normally restrained from meshing.

by a bar or cam 11 .on which normally rests a lug I9 fixedly extending from said gear 12. Said element 11 will be hereinafter more particularly described.

In the embodiment of the invention illustrated,

- a foot-pedal 88 is provided to start the operation of the apparatus. Referring to Fig. 1, this pedal 88 is suitably pivoted below the table top '2 and its rearward extension 88a is loosely'pivotally connected to a short link 8|, itself suitably pivoted below the top 2 and pivotally connected at its rear to a rod 82, extending through the top 2 and, as shown in Fig. '7, slidably held at its upper end by the frame piece 38. Upon depressing the pedal 88, the rod 82 is caused to move downwardly. Upon releasing the pedal, a spring 83, acting on a fixed collar 18, raises both the rod and the pedal to their normally inoperative positions.

Referring to Figs. '7 and 8, the rod 82 has pivotally connected thereto a finger. ortrip 84 which is provided at its free end with a laterally extending lug 85 normallyheld against an edge of the rod by a spring 83, fixed at its ends to the rod an to the trip. Said ink 88 is normally disposed above and is adapted to cooperate with a pin 88 fixed to a latch 81 held at its edges by guiding elements 88 secured to a vertical bracket- 98 supported by the frame piece 38. Said latch 81 enters a notch formed on the aforesaid bar 11 and is normally held therein by a spring 9|, fixed at its ends to the bracket and to the latch. The bar 11 is slidable in the bracket 98 and is provided with a pin 92 extending through a slot 94 (Fig. 4)

' into a recess or chamber 95 in said bracket 98.

A spring 98 is mounted in said chamber 95 and provides lateral pressure on the pin 92 for the purpose of restoring the bar 11 to its normal position of rest.

When depressing the pedal 88, the lug 85 causes the pin 88 to move outwardly thereon,

' thus unlatching the bar 11 which therefore permits the spring 18 to move the gear 12 and member 14 inwardly against the weaker spring 98 and thus lock the members 1| and 14 together.

Rotation is immediately applied to the gear 12 and shaft 88, the lug 19 riding ofi the bar 11 I which is brought back to its normal position of rest by the spring'98. The lug- 85, in its down- 80 ward movement, completely clears the pin 88, thereby permitting the spring 9| to move the latch 81. back into locking engagement with the bar 11. Upon releasing the pedal 88, the lug 85 in its upward movement is forced outwardly by 35 the pin 88 which rides inwardly thereon, finally clearing the pin, whereupon it is again brought into engagement with the edge of the rod 82 by the spring 83. However, should the pedal 88 be released before the lug 19 has left the bar 1. e. prior to the resetting movements of the bar 11 arid latch 81, the lug '85 travels in its upward movement in engagement with the rod 82 between the latter and the pin '88, finally clearing said pin which is then free to move under the action 35 of the spring 9| to its normal position of rest. It is to be particularlynoted that the gear 12 and shaft 88 are stopped rotating after having completed a full revolution, because of the declutching action, on the members 1| and 12, of

the cooperative cam surfaces formed on the members 11 and 19. Thus, each time the operator depresses the pedal 88, the gear 12 and shaft 88 are caused to rotate one complete revolution.

In mesh with the gear 12 is another gear 81 influence of a spring I88, normally meshes with the. toothed portion I81 of a gear I89. The latter is loosely mounted on .the same shaft and lateral displacement thereof is prevented by an inner fixed collar I83. This collar I85 has a pin II8 fixed thereto and extends through a pair of. apertured cam members III and H2, which cooperate with said pin H8 in a manner which will be hereinafter more clearly understood. One of, these members, II I, is fixed to the frame piece 38 and the-other, I I2, is loosely or rotatably held in the fixed member by an apertured bracket II4 secured to said frame piece 38. A handle I I5, extending from the movable member through a slot in the frame piece 38, is provided with a spring-pressed pin II 8 slidably cooperating with a curved rack II1 (as best illus trated in Fig. 9), this construction permitting is I 'the front of the apparatus. As best illustrated in Fig. 6, the fixed member III is formed with a circular track II9 having an arcuate tooth or raised cammed portion I20 and the adjustable member H2 is similarly formed with a circular track- I2I also having an arcuate tooth or raised Said raised portions I20 and I22 overlap one another for any position of the handle 5.

It being observed that the collar I05 rotates one complete revolution only, each time the pedal 80'is depressed, the position of the pin. I I0 is by necessity the same at the start and at the end of such rotation. This normally inoperative'position of the pin IIO is shown in the drawings, namely on the low portions of both tracks I I9 and- I2I and adjacent to the raised portion I20 of the fixed member III. Upon depressing the pedal 80, the pin II]! is carried in the direction of the arrow in Fig. 6, riding on both of said low track portions until it reaches and is raised by the cammedportion I22 of the adjustable memher 2, this causing the member I05 to become separated from the member I01 against the force of the spring I06. The gear I09 stops rotating,

but the pin II 0 continues rotating with the collar I05, firstriding on said raised portion I22 alone, then on both raised portions I22 and I20, and then only on the raised portion I20 of the fixed member III. It finally slides off the latter cammed portion I20, its rotation beingarrested at the instant it assumes its original position shown in the drawings, with the clutching mombers I05and I01 in mesh. It now becomes 'ap- 'parent'that the rotation of the gear I09 may be controlled, 1. e. its extent of rotation varied, by adjusting the position of the handle II5.

Referring particularly to Fig. 4, the gear I09) meshes with a smaller gear I24 fixed to a' shaft I25 rotatably mounted, in axial alinement with the platen roll 4, in a bearing or support I26 fixed to the side plate 8. Said gear I24 and a fixed collar I21 prevent lateral displacements of the shaft I25. Said gear I24 is "provided, at its side facing the platen roll 4, with a toothed hub por tion or clutching member I 29, and the usual shaft fixed to the platen roll 4 is provided at its left with the usual knurled wheel I30, but in addition fixedly carries [a clutching member I3I, which meshes with the member I29 when the typewriter carriage is in its extreme left position.

, -'Assuming, for the purpose of the present de- I scription, the typing of a sheet in the typewriter to have been completed, the operator depresses the usual mechanism (not shown) for releasing the carriage so'that it will move to the left, the usual stop (not shown) being soadjusted that the carriage is caused to move the entire extent of its possible travel, (In the usual typewriter construction, the carriage releasing mechanism may comprise a latch or key on the carriage, but, with proper adjustments, a key on the keyboard or either one of a plurality of keys on the keyboard may be caused to effect motion of the carriage to its extreme left, position.) With the members I29 and I3I in mesh, the operator depresses the pedal 30, which causes the platen roll 4 to rotate to the extent determined by the position of the control H5 and such sheet to be progressively ejected as a result of this rotation, being caught, priorto interruption of rotation, by the first cooperating roller pair 20 of the conveyer 1 to be transferred by the latter into the sheet storage magazine I2.

Slidably keyed to the inner end of the shaft 66 is a clutching member I32, and in alinement with said shaft 66 'is another shaft 61 rotatably car- 55 63 prevent axial displacement of said shaft 61. 10

Said wheel I36 will be hereinafter more-particularly described. During the operation of the apparatus, when it is used to automatically feed sheets to and position them on the platen roll, said members I32 and I 34 are kept in constant mesh by a control I1 I, also to be hereinafter more particularly described. Obviously, with the mem bers'l32 and I34 in mesh, each time the pedal 80 is depressed, the shaft 61 is caused to rotate, as v the shaft 66, one full revolution, its rotation 20 thereafter being also immediately arrested. I Referring to Figs. 4 and 11, a wheel I31 fixed tothe shaft 61 is formed with a cam-groove I38, and alever I30, having aslotted head I40 mounted on the shaft 61 so as to be guided thereby, carries a roller I4I eooperating with said groove I38. A collar I42 is fixedly secured to the shaft 61 adjacent the outer face of the lever head I40, to keep the roller in the groove. .-The lever I39 at its other end (see Fig. 1) is pivotally connected to a -30 .pivotal arm I44 fixedly extending from a shaft I45 suitably mounted,in the side plates 8 and 8a, said arm I44 forming a bell-crank construction through the shaft I45 with the aforesaid pair of suction sheet gripping and feeding devices I6 35' i (only one being shown),'also fixedly extending from said shaft I45. The devices I6 are normally positioned with their sheet gripping shoes I6a in engagement or substantial engagement with the top sheet of-the stack, the cooperating groove I38 and roller I4I obviously creating re'ciprocating motion of the lever I39 and thus rocking inotion of said shoes. They are of standard, construe-1 tion, the suction necessary for their operation be-' ing created through a suitable conduit I46 and in the usual manner being intermittently applied to their shoes. The usual means is provided for directingair currents .upon the upper sheets of the stack I0 at their edges to cause the'top sheet to become separated, thus permitting the devices. 50

I6 to grip and transfer to the conveyer G'only a single sheet at a time, each time they are made to operate. This means is schematically illustrated by the air nozzle and. conduit I41.

It being observed that, with the members I32 conveyer 6, and immediately thereafter onlyonce. V

in the opposite direction, causing the shoes Ilia to be brought back to their inoperative positions on the remaining stack of sheets. Thu s, each time the pedal 80 is depressed, a single sheet istransferred by the shoes ISa from the magazine 7 I I I to the conveyer 8 t6 be conveyed thereby to the platen roll 4, which as previously stated must then be in its extreme left position. This single cycle of motion of the rod I39 occurs at a predeter mined time duringthe operation of the apparatus, as will be hereinafter more particularly described.

Referring to Figs. 4' and 10, another camgrooved wheel I49 is slidably keyed to the shaft 61 and its groove I50 cooperates with a roller I54 carried by a second slotted lever I5I moimted on the shaft 61 so as to be guided thereby. Both the wheel I49 and lever I5I are caused to move with the typewriter carriage by a pair of apertured brackets I55 slidably mounted on the shaft 61 and fixedly secured to the rear surface of the typewriter guide plate 5. A washer or spacer I56, positioned between the lever I5I and one of the brackets I55, keeps the roller I54 in the groove I50. Referring to Figs. 10 and 12, the lever I5I at its other end is pivotally connected to a pivotal arm I51 fixedly extending from a shaft I59 pivotally mounted at its ends into brackets I60 fixed to the plate 5. Also fixedly extending from the shaft I59 and forming a bell-crank construction with said arm I51 are a pair of arms I6I carrying a spring-pressed'roller I 62, which normally cooperates with the platen roll 4 through the.

aforesaid slot 6. Another arm I64 is pivotally attached to the lever I5I and is fixed at its other end to another shaft I65 pivotally mountedinto brackets I66 fixed to the plate 5. Fixed to the shaft I65 are a pair of arms I61 each of which carries at its end a spring-pressed finger I69. Thev two fingers I69 are also operative through the slot 6', but are normally spaced from the platen' roll 4.

The function of [the fingers I69, as will be hereinafter more clearly understood, is to stop a sheet in its descent from the conveyer 6 down the guideplate 5. I deem this feature of my invention to be an important improvement in the art of automatically feeding sheets to a typewriter and positioning them on itsiplaten roll, inasmuch as it not only properly alines the edges of the sheets relatively to the axis of the platen roll, but also assures their location, at any instant during their subsequent travel in engagement with the autom'atically rotated platen roll, to be definitely corelated to the various elements necessary to position them automatically on the platen roll, so that each sheet inturn maybe caused to occupy the same positionat the end of its automatically produced motion on the platen roll. That in turn permits any size sheet to be advanced to writing position on the platen roll, by suitably adjusting the extent of rotation of the platen roll.

With the-members I32 and I34 in mesh, the wheel I49 makes one complete revolution each time the apparatus is operated by the pedal so that the position of the roller I54 in the groove I50 is' the same at the start and at the end of such rotation. Now the groove 150 is so designed that, during'such rotation, the lever I5I is carried only once in one direction, causing the fingers I69 to engage the platen roll 4 and the roller I62 to become separated from the platen roll 4, and thereafter only once in the opposite direction, causing the fingers I69 and the roller I62 to be restored to their normal po- Referring to Figs. 4 and 22, still another camgrooved wheel I82 is provided on the shaft 61 to which it is secured. The roller I 84 cooperating with its groove I83 is carried by a third slotted lever I85 mounted on the shaft 61 so as to be guided thereby. A fixed collar I86 keeps the roller I84 in the groove I83. As illustrated QinFigs. 1 and 23, the lever I85 at its other end is connected to one arm of a bell-crank I81 pivotally carried by a vertical frame plate I88 ex-- tending from the base 2. The other end of the 5 provided with an inner arm I94 which is weight- 15 I ed and normally held in an uppermost position by a vertical latch I95 fixed to a shaft I96 piv- J otally carried in standards I 91 secured to the plate I88. The rocking member I92 .comprises still another arm I98 which has pivotally mount- 20 ed thereon a pawl I99 cooperating with a ratchet wheel 200 fixed to the shaft I93. Asshown in full lines inv Fig. 24, the normal position of the member I92, 1. e. its position when held against gravity by the latch I95, causes the pin carried 25 by the outer arm I9I to be located at the bottom of the slot I. As will be hereinafter more particularly described, upon a rocking movement of the inner arm I94 and an upward movement of the lever I89 to their respective positions in- 30 dicated in dot and dash lines, the weight of the inner arm I94 causes said pin to ride with the lever I89 at the top of the slot I90 and the pawl I99 to be set back a tooth, on the ratchet 200.

Referring particularly to Fig. 1, another rock- 35 ing shaft 20I is mounted at one end in the standard I91 and at the other in a standard 202. A block .203, adjustably secured to said shaft 20I, fixedly carries a bent rod 204 to the outer end of which a finger 205 is adjustably secureda The 40 finger 205 rests on the upper surface of the supply-sheet stack I0 and gradually drops, exerting a torque on the shaft 2!, as the height of the stack is diminished by successive sheet deliveries to the conveyor 6.. The block and finger-adjust- 45 ments permit the finger to be cooperatively po sitioned on the stack I0 in accordance with the size of the sheets it contains. The turning movement of the shaft'20I causes a corresponding rocking movement of ,an arm 206 fixed thereto and slidingly cooperating with a pin carried'by an arm 201 fixed to the shaft I96. The uppermost position of the arm 201 is limited by a pin 208 fixed to the standard I91.

A worm 209, fixedly mounted on the shaft I93, meshes with a worm-wheel 2I0 secured on a shaft 2 rotatably'mounted at its ends in bear ings carried by the frame plate I88 and by another frame plate (not shown). respectively. The shaft 2. also fixedly carries a sprocketwheel 2 I2 cooperating with a sprocket chain 400, oneend of which is connected to the magazine II and the other end to a balancing weight 40I. The magazines II and I2 are-rigidly carried by vertical rod-supports 402 and'403, respectively.

These supports are mounted in and guided for vertical movement by bearing-members 404, but

With the members I32 and I34 in mesh, the wheel I82 rotates one complete revolution each time'the pedal 89 is depressed by the operatorso that the position of v the roller I84 in the groove I83 is the same at the start and at the.

' lever I85 occurs at a predetermined time during the operation of the apparatus, as will be hereinafter more particularly described. When the weighted member I92 is in its position shown in full lines in Fig. 24, i. e. in looking engagement with the latch I95, these displacements of. the rod I89 have no effect on said member, because of the slot and pin connection'of these parts, the pin merely riding first to the top, then to the bottom of the slot I99. However, after a certain number of actuations of the pedal 89,-causing removal of a corresponding number of sheets from the supply stack I 9, the lowering of the fin:

ger 295 will have caused the latch I95 to have swung out of locking engagement with the member I92 through the-intermediary of the rocking elements 204, 20:, 206, m and we, permitting said member to swing under the influence of its weight until limited in such movement by its pin striking the upper end of the slot I99. Thus, the following operation of the pedal 89 causes the member I92 to swing further in the same di-' rection during the upward movement of the rod I89, the total angular displacement of said member causing the pawl I99 to be positioned on another tooth of the ratchet 299. The downward movement of the rod I99 then carries the member I92 to its normal position, and in this returnmovement ofrsaid member the shaft I93 is pre-- determinedlyrotated by the action of the pawl I99 on the ratchet 299. The shaft 2 is correspondingly rotated through the intermediary of the worm 299 and worm-wheel'ZIO. The corresponding rotation of the sprocket-wheel 2I2 raises the magazine 2| I, through the intermediary of the chain 499, bringing the upper surface of the stack II) to its former level. The finger- 295 is thus brought back to its former position, and in this return movement the arm 296 is caused to swing back to its lowermost position, permitting the arm 291 to follow suit by action of gravity and the latch to be correspondingly restored beneath the weighted arm I94. Obviously. each time the supply magazine I I is raised in this manner, the storage magazine I2 is lowered cor-- respondingly the'same distance. The above-described mechanism for moving the magazines II and I2 permits the use of work sheets of varying thickness.

A hand-wheel 4I9 (Fig. 1) is provided at the rear end of the shaft499 for adjusting the respective positions of the magazines II and I2.

Before operating this wheel to lower the magazine II and elevate the magazine I2, the pawl I99 must be swung out of engagement withits ratchet 290. Obviously, the starting positions of the magazines II and I2 are adjusted in accordance with the height of the stack of work sheets with which the magazine II has been supplied.

Assuming the operator to have completed his or her work of addressing a sheet on the platen roll 4, upon actuating the usual typewriter carriage releasing mechanism (not shown), the

wh el I49, the lever I5I and the parts carried by s d lever are moved by the typewriter carriage to their extreme left positions on the shaft 61, because of theirbeing guided thereon by the 5 brackets I55. Upon depressing the pedal 89, no movement is imparted to the levers I39 and I5I by their respective cooperating grooves I38 and I59 fora certain period of time, during which the roller I62 cooperates with the platen roll 4 10 in causingeiection of the addressed sheet and the platen roll 4 is sufficiently rotated to,permit the addressed sheet, regardless of its size, to travel g past the fingers I69. 'At the end of that period, the first movement of the lever I39 occurs, which 15 causes a new sheet I9 to be transferred to the conveyer 6 to be discharged thereby on the guide and advancing the fingers I69 on the platen roll 4 so as to block further ingress of the new sheet.

The second movement of the lever I39 occurs immediately after its first, as-has been seen, 25 which restores the shoes I611 to their normal positions over the stack I9. Thereafter, the movements of the lever I95 take place in quick V succession, which may or may. not cause reposi= tioning of the magazines II and I2, as has been explained. On the other hand, the groove I59 is so constructed that its cooperating lever Ibl is maintained inactive upon completion of its first movement for a slight period of time, during which the new 'sheet travels through the conveyer 35 .6 and onthe plate 5 to be stopped by the fin= gers I69. At the end 'of this period of inactivity, the lever I5I undergoes its second movement, which quickly removes the fingers I69 out of en= gag'ement with the platen roll, permitting further 40 travel of the new sheet, and simultaneously quick= ly moves the roller' I62 to a position on the platen roll 4 with the inner edge portion of the new sheet therebetween. In other words, the fingers I69 are caused to clear the inner edge of the new sheet substantiallyat the instant the roller 462 comes into contact with the paper. At that same instant, the platen roll 4, which has been contin= uously rotated and has either partially or wholly ejected the addressed sheet, causes the new sheet, 50

in conjunction withthe roller I62, to travel in= wardly on its surface. The'new sheet finally comes to rest, properly pomtioned on the platen roll 4, when the latter stops rotating, such interruption of rotation occurring, as has already been explained, when-the clutching member I95 is forced to become separated from its cooperat= ing member IN by the action'of the pin M9 on the adjustable, cam I22. Obviously anyone of various size sheets may be accurately positioned, in the manner deseribedyonthe platen roll 4, by properly adjusting the position of the handle I I5, which controls the extentoi rotation of the platen roll 4. The grooves I38, I59 and I83 are evidently 5 so constructed that the levers I99, I5! and I95 are caused to remain inactive upon completion of their respective second movements, the wheels I31, I49 and I82 coming to rest with the rollers I4I, I54 and I84 normally positioned zjelatively 7o It now becomes apparent from previous de scription that, with the typewriter carriage in its extreme left position, the same control, namely the pedal 80, operates to automatically transfer the top sheet of the stack III from the magazine II. into the typewriter I, without manual rotation of the platen roll 4 being required for 10- cating it in its proper typing position thereon, and to simultaneously automatically remove the already positioned and addressed sheet and convey it for storage in the magazine I 2 in its order of succession with relation to the sheets already stored therein. Withthe new sheet in place on the platen roll, the operator moves the carriage in the usual manner to the right to the position required to start typing on such sheet. During this typing period, the roller I62 cooperates with the platen roll 4 and travels with the typewriter carriage, as in the usual typewriter construction. Should the member I3I on the platen shaft come in contact with the member I29 at the end of a line, the usual typewriter carriage line-spacing lever I10 (Fig. 1) may nevertheless be operated to return the carriage to begin a new line, i. e. to again move the carriage to the right and to rotate the platen to advance the sheet thereon to a position for receiving the next iine of typing. In this manner, successive sheets of the stack I may be, seriatim, carried to writing position in the typewriter, typed upon, removed from the typewriter and stored. By controlling the extent of rotation of the platen roll with the handle H5,"

as when it is desired to operate said projecting apparatus, but to insert and remove sheets in and outof the typewriter I in' the usual way by hand, to disengage the clutching members I32 and I34 to render the shaft 61 and the parts actuated thereby inoperative. This .isaccomplished by the control I1I which, as shown in Fig. 3, is operated from the front of the apparatus. As illustrated in Figs. 4 and 5, it is pivoted to a bracket I12 fixedly extending from the support I00 and, as illustrated in Figs. 4 and 7, its inner end carries a pin I14 adapted to ride in a circular groove I15 in the member I32. The control "I also carries a pivoted detent I16 adapted to cooperate with either one of twoopenings I 11 'and I18 formed in an extension I19 of the bracket I26. When moved to cause said detent to drop into opening I11, it looks the member I32 to the member I34, and when moved to cause said detent to drop into opening I18, it separates the member I32 fromth'e member I34. When so rendered inoperative,the shaft 61 is'provided with a means to prevent rotational displacement thereof, which would otherwise cause the camgrooves I38, I50 and I83 to lose their proper positions relative to the actuating gear 12 and thus toproduce improper movements of the levers I39, II and I85 and parts controlled thereby, when again the apparatus is operated to automatically matic rotation of the shaft 61, the spring IN '01 friction belt 245'.

of the conveyer 1 may be raised, but the auto- 5 matic rotation of the platen roll 4 may still be utilized for ejecting such sheets therefrom. Also, by operating, the control "I to declutch the members 132 and I34, blanks may be positioned by hand on the guide-plate 5 and the automatic rotation of the platen roll 4 used for properly positioning them thereon. For such occasions, the control 56 (Fig. 16) may, if desired, be operated to stop the conveyer rollers rotating.

Referring to Fig. 1 a magnifying lens or optical system of lenses 220 transmits a divergent beam of light from a light source or lamp 22I, which beam after reflection from a mirror 222 is projected on the rear surface of a translucent screen 224. The latter, as shown in Figs. 1 and 20 3, is so positioned as to be readily observable by the typist during his or her work at the typewriter I. The lamp 22I is housed beneath the base 2 within a box 225, which is provided with an apertured end 226 for the passage of rays. A 25 dark-box 221 for housing said beam comprises an axially vertical rear section 221a projecting upwardly through the base 2 and carrying. at its lower end the optical projecting means 220 beneath said base and an axially horizontal upper section 221D extending forwardly from said rear section 221a and carrying at its forward end portion the screen 224 between apertured plates or frames 229. This box 221 increases in cross-sectional size from the projecting means 220 to the screen 224 to permit unobstructed passage of the divergent beam, the mirror 222 being interiorly disposed at 45 degree angles with the respective axes of the two sections of said box 221.

As best illustrated in Figs. 17 and 18, a light transmitting band or film 230,'such as is used for motion picture projection and the picture areas or portions of which have the addresses or desired records photographed thereon, is mounted on the usual reels 23I and 23 I for travel from one to the other between the optical device 228 and the apertured end 226 of the light-box 225. As shown in Fig. 19, the reel 23I is removably keyed to a spool 232, rotatable on a fixed shaft 234. The latter is carried by a vertical frame plate 235, fixedly mounted beneath the base 2. A nut 236 maintains the reel 23I on its spool 232, and a pair of pins 231 riding in a circular groove 239 maintain the spool 232 on its shaft 234. ,A rear spring 248, acting through the medium of a loose washer, has the effect of a brake, causing resistance to rotation of the spool 232 and reel 23I carried thereby. Similarly, the reel 23I'fis removably keyed to a spool 232 and held thereon by a nut 236'. The spool 232 is similarly rotationally mounted on a fixed shaft 234', also extending from the plate 235. In. like manner, a spring 243' functions to restrain rotational move: ment of the spooll232' and reel 23 I thereon. The

film 230, in its travel from one reel to the other,

passes over a pair of sprocket wheels 2 and 24I', the cogs of which cooperate with the usual openings 24-2 disposed along one of the marginal edges of said film. In a manner which will be more clearly understoodthereinafter, pulleys 244 and 244' respectively cooperate with the wheels 24I and 2H, pulley 244 being connected with the spool232 by a. slip or friction belt 246 and pulley 244' being connected with the spool 232' by a slip 76 Referring to Figs. 18 and 20, a'shaft 246 is rotatably mounted in rear bearings 241 fixed to the plate .235 and carries a gear 248 rotatable therewith. As will be seen, this shaft 246 is successively actuated at the right moments, to produce successive displacements of the film 230 in one direction or the other behind the lens or lenses 220, its extent of rotation being one complete revolution and its direction of rotation the same on each occasion. Also fixed to the plate 235 at the rear thereof, are a pair of bearings 249, in which a shaft 250 is both rotatably and slidably mounted. The shaft 250 fixedly carries at its ends bevel gears 25! and 25! and also fixedly carries between said bearings 249 a centraljgear 252 constantly meshing with the gear 248. Said gear 252 is provided with a hub portion formed with a groove 254 in which rides a pin 255 fixed to the rear portion of a control 256 extending through the plate 235. This control 256 is pivoted toa front bracket 251 extending from the plate 235 and is provided with a spring-pressed pin 259 adapted to slidably enter any one of three recesses 268 formed in said bracket 251. When the pin 259 is caused by the handle 256 to engage the opening 260 at the right in Fig. 18, the gear 25! is caused to mesh with a cooperating bevel-gear 26!, and when the pin 259 is caused by the handle 256 to engage the opening 260 at the left in said figure, the gear 25! is caused to mesh with a cooperating bevel-gear 26!. When the control is operated to cause the pin 259 to drop into the center recess 250, both gears 25! and 25! are out of mesh with their respective cooperating gears 26! and 26!. The latter gears are respectively fixedly mounted at the rear ends of shafts 262 and 262', extending forwardly through the plate 235 The gears 26! and 26! and fixed collars 264 and 264' prevent the shafts 262 and 262 from becoming axially displaced. Shaft 262 carries the aforesaid wheel 24! and pulley 244 and shaft 262' carries the aforesaid wheel 24! and pulley 244'. The wheels 24! and 24! are fixed to their respective shafts,but the pulleys 244 and 244' are slidably mounted thereon to permit them to be moved into and out of mesh with their respective cooperating members 24! and 24! under the influence of controls 265 "and 265'. As shown in Fig. 20, the control 265 is pivoted to a fixed bracket 266 extending forwardly from the plate 235 and carries a pin riding in a circular groove 269 in the pulley member 244. A rearward extension 210 is provided with a spring-pressed pin-21! adapted to slidably enter either one of two recesses 212 formed in the bracket 266. In construction and operation, the control 265' is identical to the control 265 described.

Observing the direction of rotation of the actuating shaft 246 (that of the arrow in Fig. 20), it now becomes apparent that, with the control 256 thrown to the extreme right in Fig. 18 and the controls 265 and 265 respectively positioned to lock the pulley 244 to the sprocket wheel 24! and to unlock the pulley 244' from the sprocket wheel 24!, a rotation of said shaft 246 will cause a corresponding rotation of both the sprocket wheel 24! and pulley 244 in such a direction as to unwind the film 230 from the reel 23! and wind it on the reel 23!, the sprocket wheel 24! causing a displacement of the film 230 exactly in proportion to the extent of rotation of the shaft 246 and the slip belt 245 permitting the amount of film displaced to be wound on the reel 23!. In the meanwhile, the sprocket .wheel 24! is rotated idly by the film 230 and the pulley 244' is rotated idly by the belt 245'. By throwing the control 256 to the extreme left in Fig. 18 and reversing the positions of the handles 265 and 265', the same rotation of the actuating shaft 246 will nowcause the sprocket wheel 24!, the

pulley 244' and the slip belt 245' to move the film 230 the same amount in the opposite direction and wind this amount on the reel 23 The gears 248 and 252 are so designed that, for each rotation of i the shaft 246, the film 230 is caused to advance,

in one direction or the other depending on the positions of the controls 256, 265 and 265', the distance of one of its picture areas, so that, as will be hereinafter more clearly understood, the picfilm taking place by actuation of the shaft 246.

Moreover, the film 230 can then be displaced by a crank 214 positioned on either one or the. other of the sprocket wheel ends 215 and 215', depending on the positions of the controls 265 and 265' orthe direction of travel desired, so that, when- 5 ever desired, any particular picture portion may be brought into position before the lens or lenses. Idlers or friction wheels 216 and 216' bear down on the sprocket wheels 24! and 24! for maintaining the film thereon and may be pivoted out of the way by respective handles 211 and 211'.

Referring to Fig. 16, the support 29 is formed with another bearing portion 219 in which the motor shaft is rotatably carried. Said motor shaft also extends through another support 280 and loosely carries between said supports a worm 28!, which meshes with a worm-wheel 282 loosely mounted on the aforesaid shaft 246. The worm 28 is formed at one side with a toothed portion 284 to cooperate with a spring-pressed clutching 40 member 286 slidably keyed to the motor shaft. Axial displacement of the worm 28! is prevented by an inner collar 285 fixed to the motor shaft. A control 289 pivoted to a bracket 290 extending from the support 29 operates on the member 286 to either separate it from or mesh it with its cooperating member 284. The control 289 is provided with a spring-pressed detent 29! to engage an opening inthe bracket 289 for maintaining the member 286 in its declutched position. The control 289 is moved to its clutching position causing the members 284' and 286 to mesh, when it is desired to displace the film 230 by actuation of the shaft 246.

Referring to Fig. 1, the shaft 246 is rotatably carried by other supports 292 fixed to the base 2. Axial displacement of this shaft is prevented by fixed collars 294. The wheel 282 is provided at one side with a clutching portion 295 to cooperate with a clutching member 296 slidably keyed to the shaft 246. Axial displacement of this wheel is prevented by an inner fixed collar 291. Move-' ment of the member 296 to force it in meshing engagement with the member 295 is provided by a spring 299, properly positioned on the shaft 246 by a fixed collar 300, but the member 296 is normally restrained from such movement by a bar 30!, on the cam end of which normally bears a pin 302 outwardly extending from the member 296. The bar 30! is slidably mounted in a support 304 fixed to the base 2 and is provided with a notch normally engaged by a latch 305 slidably guided on the support 304. The latch 305 is actuated, as will be seen, at a predetermined moment to release the bar 30!, which then moves with 7 the pin 302 and member 296 under the influence of the spring 299. Upon rotation of the shaft 246, the pin 302 rides off the bar 30I, which is then restored to its normal position by a spring 306 acting on a pin-301 fixed to the bar 30I. The spring 306 is attached at one end to the support 304 and the pin 301 projects through a slot 309 formed in said support 304.

Referring to Figs. 4 and '7, the shaft 66 carries at its outer end'a gear 3 removably secured to said shaft, as by a key 3 I2 and nut 314. The gear 3 meshes with a gear 3I5 removably mounted on a fixed shaft 3I6 (Fig. 9), extending from thetends through the base 2 and is pivotally attached at its lower end to one end of a link 32I pivotally carried beneath the base .2. The link 32I at its other end is pivotally attached to another link 322, which is pivotally connected to and serves to actuate the latch 305. A spring 324, acting on a collar 325 fixed to the rod 320, maintains the latch 305 in its normal lowermost position engaging the aforesaid notch in the bar 30I, the rod 320 then being in its normal uppermost position.

Each time the arm 3I1a is actuated by the pin 3I9, the downward movement of the rod 320, against the force of the spring 324, causes the latch 305 to unlock the bar 30 I, this, as has been seen, permitting theshaft 246 to rotate, the control 239' being assumed in clutching position. Upon the pin 302 riding off the bar 30I and the pin 3I9 riding ofl the arm 3I1a, the latch 305 is restored to its normal position in looking engagement with the bar 30 I, by reason of the action of the springs 306 and 324. The shaft 246 rotates exactly one revolution, further rotation being prevented because of the cam action of the bar 30I on the pin 302, which, causes the latter to declutch the member 296 from its cooperating member 295, as well as resume its normal position on the bar. This full revolution of the shaft 246, as has been seen, displaces the film 230 and brings another of its picture areas into position before the projecting means 220.

bviously, the gears 3| I and 3I5 are caused to be rotated each time the pedal 30 is depressed by the operator. However, in view of the fact that the film 230 may bear a given number of addresses or records in each of its picture portions,

it may not be desirable to have the pedal 00 cause actuation of the shaft 246 each time or on everyv occasion it is depressed, but only after all the projected records of one picture area have been copied on the typewriter. Now, observing that the gears 3| I and 3 I go through the same extent of rotation each time the pedal is depressed, it follows that they may be so chosen as to cause a definite relation between the number of times the pedak is depressed and-the number of'times the shaft 246 is actuated. Thus'fthe number of records in a picture area of the film dictates the ratio of pitch line diameters or of number of teeththe gears 3H and 3|! should bear. In the embodiment of the invention illustrated, the gear 3I6 carries six times as many teeth as the gear 3I I. Observing that the gear 3 rotates with the shaft 66 one complete revolution each time the pedal 30 is depressed, consc- 346 at its upper end is pivotally attached to a quently the shaft 246 is rotated and the film 230 displaced the distance of one of its picture areas once for every sixth time the pedal 00 is depressed. This arrangement of gears 3| I and 3I5 evidently provides for six records in each picture 5 portion of the film. Should the succeeding film or a particular sequence of the same film differ in the number of records per band portion, the gears 3I I and 3 I 5 are replaced by a new set bearing the proper ratio to one another, the replacing 10- gear 3| 5 being also provided with a pin 3| 9. For example, if it is desired to have the advanced to cause a different picture area to be positioned for projection each time the pedal is operated, the

new gears 3II and-3I5 should be identical to one another.

Preferably, the idle position or positions of the pin 3I9 are such that it bears against or is close to the crank arm 3I1a prior to the rotation of the gear 3I5 causing displacement of the film, so that said pin may rock said arm at the start or soon after the start of such rotation. Obviously, the radial positiomof the pin 3I9 and the construction of the arm 3I1a are such as to permit the use of different size gears 3I5. As best illustrated in Figs. 13 and 14, a shutter or band 326 of suitable sheet material, such as the trade product known as "celluloid, is mounted for travel behind the screen 224 between two rollers 321 and 329 rotatably mounted in the side walls of the casing portion 221!) and to which opposite end edges of said band are respectively secured. The lower part 326a of this band is opaque, except at a central portion 330, which is transparent and of such dimensions 'as to permit projection, on the screen 224, of only one of the addresses or records contained in a picture area of the film 239 (see Fig. 3). The upperpart 3261), shown wound on the upper roller 329 in Figs. 13 and 14,- is transparent and, aswill be 40 seen, maybe caused to be positioned behind the screen 224 to permit projection thereon of the entire extent of each picture area. The upperroller 329 is equipped with a spring 33I, which serves to wind the shutter on the surface of said upper roller, as well as to keep it taut between the two rollers. A pin 332 fixed to thelower v roller 321 cooperates with an adiustabIe stop or crank-arm 334 to arrest or limit the winding action of the spring 33I. This stop 334 is formed at the inner end of a' rod 335 threaded through the front of the projector box and carrying a hand-wheel 336 at its outer end. A lock-nut 331 secures the rod in its adjusted position.

The lower roller 321 is provided at one side with a ratchet wheel 339 fixed to its shaft. Normally engaging said ratchet 339 are a pair of dogs, 340 and 3, the respective purposes of which are to, intermittently displace the two rollers and shutter and to maintain-those parts in their displaced positions, against theforce of the spring 33]. As will be more clearly understood, at a predetermined moment these dogs are caused to disengage the ratchet 339, the rollers and shutter then returning under the influence of the spring 33I .to their original, positions, as

determined by the adjustable stop 334. Thus. the first or uppermost position of the transparent shutter portion 330 back of the screen,224 is adjustable by the hand-wheel 336.

Referring to Figs. 4 and 5, theaforesaid mem-' ber III carries a crankstud 345 on which is pivotally mounted the lower end of a link 346. Referring particularly toFigs. 3 and 15, the link crank or rocking arm 341 fixed to a horizontal shaft; 349 carried by the side plates 9 and 911 at their upper edges. This shaft 349 has also fixed thereto a similar arm 359 to which is pivotally attached the lower end of a link 35! (see Figs. 1 and 2). As best illustrated in Figs. 13 and 14, this link 35! extends through an aperture in the projector box and is pivotally carried at its upper end by a bolt 352 adjustably secured, as by a nut 353, in the slot 354 formed in a lever or crank 355 loosely carried by the shaft of the lower roller 321. Access to the nut 353 for its adjustment is had through a side door 351 (Fig. 2) of the projector box 221. The crank 355 carries at its end the dog 349, a spring 356 attached to that dog 349 and to the crank 355 causing the dog 349 to normally engage the ratchet wheel 339.

As illustrated in Figs. 1 and 9, a link 353 is pivotally attached at its lower end to the arm 3!1b of the bell-crank 3H. Referring to Figs. 1 and 15, this link 358 at its upper end is pivotally attached to a crank or rocking arm 359 fixed to a second horizontal shaft 369 carried by the side plates 8 and 8d at their upper edges. A similar arm 35! is fixed to the shaft 369 and to this arm 36! is pivotally attachedthe lower end of a rod 342. As shown in Figs. 13 and 14, the rod 342 at its upper end portion extends through an aperture in the projector box through the outer arm 362a of a pivoted link 362, the inner end of which is adapted to slidably cooperate with the outer arm 349a of the dog 349. The rod 342 further extends through the outer arm saw of the dog 34!, which is pivotally carried by a fixed bracket 364. A spring 365, attached to the arm 34la and to a fixed bracket 366, causes the dog 34! to normally engage the ratchet wheel 339. Fixed collars 361 and 369 are carried by the rod 342 and are so positioned that, upon their downward movement with the rod, they act against the force of the springs 356 and 365 to rock the arms 362a and 3am and thereby cause the dogs 349 and 34! to move out of engagement with the ratchet 339, respectively. Upon release of the rod 342, the springs 356 and 365 restore the dogs to their normal positions on the ratchet-333.

The rod 359 is actuated only when the apparatus operates to displace the film 239 as a result of the pin 3!9 striking the bell-crank arm 3!1a., and on each of these occasions is caused to quickly move downwardly and acts, through the intermediary of the crank 359, shaft 399, crank 39! and rod 342, to release the ratchet 339 from the dogs 349 and 34!, said rod 358 and parts movable therewith being obviously restored by spring action to their normal positions when the pin 3l9 leaves the surface of the arm 3!1a. 0n the other hand, observing that reciprocating motion is imparted to the rod member 346 by a rotation of the crank member !9! and that the latter rotates one complete revolution during each operation of the apparatus (the gears 12 and 91 hearing a one to one ratio to one another), said rod 346 acts, through the intermediary of the crank 341, shaft 349, crank 359 and rod 35!, to move the slotted lever 355 once in one direction and thereafter oncein the opposite direction to its starting position, each time the pedal 89 is depressed by the operator. Now, during each operation of the apparatus which does noteflect release of the ratchat 339, the first movement of the lever 355 causes the dog 349 to rotate the ratchet 339 and roller 331 to lower the position of the transparent shutter portion 339 back of the screen, and the second movement of the lever 355 brings the dog 349 back into initial position on the ratchet 339, held in its displaced position by the dog 34!. The ex tent to which the shutter portion 330 is displaced by movement of the lever 355 is determined by the position of the connecting pin or stud 352 in the slot 354, and this position is so adjusted as to accord with the number of addresses or records per picture area of the film 239, i. e. as to permit projection of a different record through the shutter portion 339 in each of its successively lowered positions. Thus, in turn each of the records of the picture portion, positioned in cooperative relation with the projecting lens system 229, is pro jected and brought into view on the screen 224. 15 When the shutter portion 339 has reached its lowermost position, i. e. when the last record of said picture portion has in this manner been ex? posed to view, the next operation of the apparatus functions not only to properly displace the 20 film 239 to bring the succeeding picture area into position before said device 229, as has been seen,

} but also to release the ratchet 339 by automatic actuation of the "rod 342, whereby the shutter portion 339 is raised by spring action to its original 25 position, as determined by the stop 334, and exposes to view the first record of said succeeding area. It is to be particularly noted that, therefore, the same control. namely the pedal 99, which operates to remove a typewritten sheet from and 30 to insert a new one into the typewriter I, also operates to move both film and shutter at the right moments to bring on each occasion a new record into view, whereby no error in the copying of records is possible.

Obviously, the pin 3!9 and the film 239 are so positioned at the start that, upon depressing the pedal, the first picture area is positioned before the lens system 229 and the shutter portion brought, by automatic release of the ratchet 339, 40 to its uppermost position.

As best shown in Fig. 13, the rod 342 is pro vided at'its lower end with an elongated slot 319 through which extends the pin or element connecting the rod to the crank 36!. Such connec tion normally rests at the bottom of said slot 319, whereby manual movement of the rod to remove the dogs 349 and 34! from their ratchet 339 is permitted. When automatic actuation of the shutter is not desired, the rod 342 maybe maintained in its ratchet releasing position by a. control, comprising a hand-wheel 31! rotatably carried by the bottom of the casing portion 221b and a projection 31m cooperating with a pin 342afixed to the rod 342. The lower roller,321 is provided at its other side with another ratchet-wheel 312 fixed thereto or to its shaft and with a hand wheel 314 by means of which it may be rotated.

A dog 315 may be pivoted into and out of engagement with the latter ratchet 312 by means of a hand-wheel 316.. Thus, with the stop 334 pivoted out of the path of the pin 332, the shutter may be woundon the roller 321, as when it is desired to position its transparent portion 32Gb back of the screen 224, for example when each of the picture areas of the film contains but a single record. When automatic operation of the shutter is again desired, the dog 315 is swung out of engagement with its ratchet 312, the control 31! is operated to restore the dogs 349 and 34! on their ratchet 339, and the wheels 336 and 314 rotated to return the stop 334 and the pin 332 to their operative positions. The wheel 314 may be used to lower the position of the transparent shutter portion 339, whenever desired. If required,

portion 330 may be positioned wherever desired back of the screen and its automatic operathereon, a screen visible from the position of the' operator at said typewriter, a plurality of records arranged in a definite order of succession, and means operating in response to successive actuations of said control for projecting said records seriatim on said screen.
